Medical Malpractice — Claims Against Doctors & Hospitals in Thailand
Medical cases are not won on the feeling that treatment went badly. They are won on records and expert opinion.
Quick answer
A malpractice claim must clear three layers: the professional standard that applied, conduct falling below it, and harm directly linked to that conduct. Several routes exist — a complaint to the professional council, remedies under the health-coverage schemes, negotiation with the hospital and its insurer, and a civil tort claim. Some matters qualify as consumer cases, where the burden is lighter. The first step is always to obtain the complete medical record before memories and paperwork scatter. We act from evidence gathering through to trial. From THB 40,000.
From THB 40,000 — From 40k — expert opinion fees are separate and vary by specialty · Evidence gathering 1–3 months; trial 12–24 months

In depth
Medical Malpractice — Claims Against Doctors & Hospitals: what foreign clients need to know
Families who come to us about treatment that went wrong almost always start with the same question: what actually happened. That question matters more than how much money might follow, because the real answer sits in the medical record — a technical document lay readers cannot parse, and one that must be requested early before the important detail scatters through the facility's systems.
The three layers to prove, and the one people overlook
First is the professional standard applicable in the circumstances — not the best in the world, but what a practitioner of equivalent training would do given the actual conditions and resources. Second is conduct falling below it. Third is harm directly linked to that conduct.
The overlooked layer is the third, because many patients already carry conditions that tend toward poor outcomes. Facilities therefore argue that the harm flowed from the underlying pathology rather than the treatment. Establishing the link needs an expert who has read the whole record, not an opinion formed from a retelling.
We tell clients plainly at the outset that if the expert opinion does not support the claim, litigating is usually not worth the time or cost — and that in many cases what a family actually wants is an explanation and a systemic change rather than money.
Getting the complete medical record
A broadly worded request usually returns a few summary pages. A good one itemises: physician notes, nursing notes, prescriptions and medication administration records, laboratory results, imaging files with the reporting radiologist's report, the operative note, the anaesthesia record, and every consent document.
Nursing notes are the most useful part and the least often requested, because they are timestamped at short intervals and typically reveal when the patient's condition changed, when the doctor was informed, and when a response came. Gaps in that timeline are the first thing an expert looks for.
The routes available, and how to choose
The first route is a complaint to the professional council, which examines ethics and professional standards. Its outcome is a professional sanction, not compensation. The second is remediation under the health-coverage schemes, which is faster and does not require proving fault to the standard a court demands.
The third is direct negotiation with the facility and its professional-liability insurer, which works best once an expert opinion and a carefully computed damages figure are on the table. The last is litigation, and some matters qualify as consumer cases, easing the burden of proof and the fees for the claimant.
These routes are not all mutually exclusive, but sequence matters greatly. Negotiating before an expert opinion exists usually draws a low offer, and filing before the record is complete usually puts the claimant behind from the first pleading.
Computing damages a court will accept
Recoverable loss divides into treatment already paid, future care supported by a medical estimate, income lost while recovering, permanent reduction in earning capacity, the cost of engaging a carer, and non-pecuniary harm within the limits the law recognises.
Where the patient dies, the statutory heirs claim, and the heads include funeral costs and loss of support for dependants, computed from actual income and the period support could reasonably have continued — not from a figure chosen at will.
The view from the doctor or facility facing a complaint
We also act for providers, and the recurring pattern is that most damage comes from communication after the event rather than from the treatment. Avoiding the family turns doubt into distrust and converts a matter that an explanation could have closed into litigation.
What we advise facilities is a clear incident-review process, contemporaneous and complete documentation, and a consent practice that explains the risks specific to that procedure rather than a standard form applied to every case.
Cost structure: government fees vs professional fees
| Item | Official fee | Professional fee | Note |
|---|---|---|---|
| Obtaining and screening the medical record | Copying charges at the facility's rates | THB 15,000–25,000 | Includes building an event timeline from the full record |
| Independent specialist opinion | Not a government fee; depends on specialty and complexity | THB 25,000–80,000 per opinion | Specialties with few available experts cost more |
| Negotiating with the facility and insurer | No fee at the negotiation stage | THB 30,000–50,000 | Works best once the expert opinion exists |
| Filing and proving the case at court | Court fee by claim value; consumer cases are exempt | From THB 80,000 | Includes calling the expert to give evidence |
Settled after a gap emerged in the nursing record
Situation: A post-operative patient deteriorated overnight and care arrived late.
What we did: We built a timeline from the nursing notes and had an expert opine on when the physician should have been notified.
Outcome: The facility agreed compensation and revised its overnight monitoring process.
Advised against suing when the expert did not support it
Situation: The family believed there was error because the outcome fell short of expectations.
What we did: We had a matched specialist read the entire record and explain complications that occur despite correct care.
Outcome: The family got the explanation they wanted and avoided the cost of a weak case.
When to act, and when waiting is fine
Request the record as soon as you have doubts
The earlier the request, the more complete the record and the clearer the timeline.
Use scheme remedies when help is needed urgently
It is far faster than litigation and often does not bar the remaining claim.
Do not file before an expert opinion exists
Medical cases without expert backing usually end in wasted time and cost.
Facilities should open communication on day one
Straight explanation prevents more cases than any legal measure.
FAQ
Frequently asked questions

No — the two run in parallel and serve different purposes.
Can I claim over aesthetic clinic surgery?
Yes, and many such matters qualify as consumer cases, which favours the claimant.
Can a foreign patient sue in Thailand?
